I've tried to compile poke with `arm-linux-gnueabihf-gcc` compiler from
debian packages (gcc:armhf). I didn't know that it generates Thumb code.

But now I know :)

    Currently the Debian armhf port requires at least an Armv7 CPU with
    Thumb-2 and VFP3D16. 

And from `arm-linux-gnueabihf-gcc -dumpspecs`:

  *multilib_defaults:
  mthumb mlittle-endian mfloat-abi=hard mno-thumb-interwork


(If you're on Debian, and want to test this, you can enable Multiarch
(https://wiki.debian.org/Multiarch/HOWTO) and then `apt install gcc:armhf`)
